Hurricane Dorian has slowed over The Bahamas, pounding the island with heavy rain and winds of 155 mph, as it dropped to a Category 4 storm.

"On this track, the core of extremely dangerous Hurricane Dorian will continue to pound Grand Bahama Island through much of today and tonight," the hurricane center said in an 11 a.m. advisory. Some areas could see up to two feet of rain, and storm surge could reach 23 inches, forecasters warned.

Videos like these are circulating on Bahamian social media. People in Abaco need help. I lost contact with a friend. The church my cousin sheltered in had the roof ripped off and they’re stuck because of flooding. #HurricaneDorianpic.twitter.com/RBs5mllvaX
